TM 9-2350-277-20-1


Helper

Helpers are needed in procedures that require more than one person. A helper may be needed to help lift objects or act asan outside observer.

If a helper is needed to perform a procedure, the INITIAL SETUP will list “Helper (H)” under the PERSONNEL REQUIREDheading.

If a helper assists with a step or substep, the step or substep will include: “Have helper assist.”

If a helper performs the action alone, the step will start with “(H):.”

Locational Terms

The terms “front,” “rear,” “left,” and “right” are used to indicate where items are located on the vehicle. The point ofreference for these terms is different for Carrier items and Power Unit items. (Carrier items are items which are not on thepower unit. Power unit items are items on the engine or transmission.)

If you are working with carrier items, use this point of reference. Think of the location as if you were sitting in the driver’sseat looking out the hatch.

If you are working with power unit items, use this point of reference. Think of the location as if you were standing at thetransmission end of the power unit and facing the flywheel. This rule applies whether the power unit is IN or OUT of thecarrier.

CORROSION PREVENTION AND CONTROL (CPC)Corrosion Prevention and Control (CPC) of Army materiel is a continuing concern. It is important that any corrosionproblems with this item be reported so that the problem can be corrected and improvements can be made to prevent theproblem in future items.Corrosion specifically occurs with metals. It is an electrochemical process that causes the degradation of metals. It iscommonly caused by exposure to moisture, acids, bases, or salts. An example is the rusting of iron. Corrosion damage inmetals can be seen, depending on the metal, as tarnishing, pitting, fogging, surface residue, and/or cracking.Plastics, composites, and rubbers can also degrade. Degradation is caused by thermal (heat), oxidation (oxygen), solvation(solvents), or photolytic (light, typically UV) processes. The most common exposures are excessive heat or light. Damagefrom these processes will appear as cracking, softening, swelling, and/or breaking.SF Form 368, Product Quality Deficiency Report should be submitted to the address specified in DA PAM 750-8, FunctionalUser’s Manual for the Army Maintenance Management System (TAMMS).

THEORY OF OPERATION 0003 00

SCOPEThis section describes how major systems and components of the carrier operate. An understanding of how each partfunctions in a system and how components relate to each other will help solve possible maintenance problems with the carrier.

POWER PLANTThe power plant consists of the diesel engine and transmission. The fuel, exhaust, cooling, starter, generator, and engine airsystems are support systems for the power plant.

DIESEL ENGINE

The diesel engine is the primary source of power for the carrier. The engine converts air and diesel fuel into energy anddelivers this power to the transmission.

STARTER

The engine is equipped with a heavy duty starter. The starter, with built-in solenoid, is used to crank the engine for starting.

GENERATOR

The generator is part of the carrier electrical system. It is driven directly by engine power. The generator charges the batteriesin the carrier when the engine is running. A regulator mounted in the driver’s compartment keeps the voltage at correct levels.

OIL SYSTEM

Oil system provides lubrication for the engine. Oil is cycled throughout the engine by a pump. The pump is located internallybehind the front engine cover. An oil filter cleans the oil, and an oil cooler reduces oil temperature.

FUEL SYSTEM

Diesel fuel is stored in two fuel tanks located at the rear of the carrier. Fuel is drawn from fuel tanks by the fuel pump whichpumps fuel through filters to the engine injectors. The injectors force fuel into combustion cylinders where it is mixedwith air and changed into energy.

TRANSMISSION SYSTEM

The carrier uses hydromechanical transmission with hydrostatic steering. The transmission has its own oil system with filtersand separately mounted oil cooler. This transmission oil system is separate from the engine oil system.The transmission delivers power from the engine to the left and right final drives. The left and right final drives are driven bypropeller shafts. The final drives deliver power to drive sprockets in the suspension system.

EXHAUST SYSTEM

Major exhaust system parts are the turbocharger, exhaust manifolds, muffler, and exhaust pipes.The turbocharger is driven by exhaust gases from the engine. The turbocharger helps the engine develop more power andoperate more efficiently. The exhaust manifolds carry the exhaust gases to the turbocharger from the engine. The muffler cutsdown engine noise and allows exhaust to escape through the exhaust pipes to outside of the carrier.

COOLING SYSTEM

The cooling system cools the engine and transmission. It consists of a fan, fan drive, fan speed control assembly, radiator,coolant pump, auxiliary tank, transmission oil cooler, engine oil cooler, and thermostats. The cooling system contains

0003 00-1Change 5

TM 9-2350-277-20-1

THEORY OF OPERATION — Continued 0003 00

approximately 14.8 gallons of liquid coolant. The liquid coolant is cycled through the engine and transmission oil cooler bythe coolant pump. This process keeps the engine and transmission temperature in a safe operation range.As coolant flows through the engine, it absorbs heat from the engine and transmission. The heated coolant then flows to theradiator to remove coolant heat. The coolant fan pulls outside air in and through the radiator to remove heat. The fan ispowered by the engine through a fan drive.The radiator auxiliary tank acts as an overflow tank to keep the cooling system from overpressurizing. It also removes airfrom the engine coolant. There is a low coolant level transmitter to signal the operator if more coolant is needed.

ENGINE AIR SYSTEM

The engine air system allows air to enter the engine. The air cleaner cleans air that enters the engine. Dust is drawn outthrough a scavenge outlet. Air is filtered through a reusable filter element before delivery to the engine. An air filterindicator shows when the element is clogged and needs cleaning or replacing. After being filtered, the air moves throughthe turbocharger and into the engine cylinders.

AUXILIARY AUTOMOTIVE SYSTEMThe auxiliary automotive system includes driver controls, fuel cells, personnel heater, bilge pumps, crew ventilation system,and fire suppression system.

DRIVER CONTROLS

The driver controls regulate the engine, transmission, and steering braking systems of the carrier.The fuel shutoff control is used to stop the supply of fuel to the engine injectors. To start the engine, the driver must open thevalve. The throttle linkages are used to control the engine speed. The gear selector allows the driver to choose the propergear for the carrier. The steering system controls the direction of the carrier. The steering control consists of a steeringwheel and linkage connected to the transmission.The brake system allows the driver to stop a moving carrier and hold the carrier in position. The braking system consistsof the service brake and the parking brake. The service brakes are hydraulic and applied by pedal. The parking brakemechanically locks the transmission brakes to prevent carrier movement. Also, the system has levers, rods, shafts, andlinkages connecting to the brake shaft of the transmission.

PERSONNEL HEATER

The personnel heater system provides heat inside the carrier. Major parts are the combination combustion chamber/heatexchanger, blowers, a fuel pump, and an electrical control and safety system. The heater operates using diesel fuel drawn fromthe fuel tanks. Fuel is delivered to the combustion chamber from the fuel pump. Outside air is drawn into the combustionchamber by one of the blowers. A blower draws air from the crew compartment into the combustion chamber. The air iswarmed by heat by the combustion process and then returned to the crew compartment.

BILGE PUMPS

Two electrically driven bilge pumps remove water and other liquids from the hull. Water enters the pumps through a screenedinlet. The pumps force water out of the carrier through outlet tubes. The bilge pumps are controlled by a switch on thedriver’s instrument panel.

HYDRAULIC SYSTEM

The ramp is raised or lowered by an hydraulic system which consists of a pump, a cylinder, a control valve, and an hydraulictank. This system is controlled by a three position valve located near the driver. Moving the valve to either RAISE orLOWER position directs fluid to the appropriate port on the ramp cylinder.

TM 9-2350-277-20-1

THEORY OF OPERATION — Continued 0003 00

FIRE EXTINGUISHER SYSTEM

The fire extinguisher system consists of two CO2 (Carbon Dioxide) cylinders, one fixed and one portable. Carbon Dioxidecan put out fires quickly and effectively. The fixed cylinder only extinguishes fires in the power plant compartment. It islocated behind the driver and is actuated manually by a handle/knob on the cylinder or by an external handle connected to thecylinder by a cable. The portable fire extinguisher is located in the crew compartment and is manually discharged.

SUSPENSION SYSTEM

The suspension system supports the carrier and delivers engine power to the road. It allows the carrier to maneuver and bestable. Suspension system parts are the drive sprockets, tracks, idler wheels, track tension adjuster, road wheels, and supportarms. Also, there are torsion bars and shock absorbers.The drive sprockets drive the tracks. They are powered by left and right final drives from the transmission. The tracksconsist of two flexible chains of track shoes. The tracks ride on the drive sprockets and are guided by idler wheels. The idlerwheels can be adjusted to maintain correct track tension.There are five pairs of road wheels per side. Track centerguides fit between each pair of road wheels. Road wheels andtorsion bars are connected to support arms. The torsion bars act as springs to keep the road wheels on the ground and fromhitting the bottom of the carrier.

ELECTRICAL SYSTEM

The electrical system provides power for the carrier. The system operates on wet cell batteries and includes charging,regulating and monitoring equipment. The batteries provide a normal operating 24 volts with an amperage capability of200 amps per hour.The batteries supply the carrier with electricity when the engine is off. All electrical power is delivered through thedistribution box. Electrical power flows from the batteries through the distribution box, cables, and wiring assemblies to theelectrical equipment. The hull is a ground for the electrical system.The generator recharges the batteries and supplies electricity while the engine is running. The generator has 200 amps perhour capability.There are several electrical subsystems within the hull. Each subsystem contains at least one wiring assembly. Majorelectrical subsystems and assemblies are:Interior and Exterior Lights. Exterior lights include standard headlights, taillights/stoplights, and blackout lights. Interiorlights include domelights and panel lights.Starting and Charging. A generator with a regulator keeps the batteries charged to operating voltage. A starter with a built-insolenoid is used to crank the engine for starting.Ventilation and Heating. All carriers have a manual open-close ventilator located at the rear of the crew compartment. TheM577A3 and M1068A3 carriers also include an electric ventilation fan controlled by a switch on the master switch panel(M577A3 and M1068A3). The personnel heater is controlled by a heater control box which provides electric power forstarting and operating the heater. The control box is connected to the carrier batteries so that the heater can be operatedwithout turning the MASTER SWITCH ON.Bilge Pumps. Two pumps, one in the front and one in the rear of the carrier, remove any water that may have entered thecarrier. Both pumps are controlled by a switch on the driver’s instrument panel.

SPECIAL EQUIPMENTFor information on special purpose kits, refer to Chapter 22.

WINTERIZATION EQUIPMENTPersonnel heaters are standard equipment on M577A3, M1068A3, and M58 carriers. Since maintenance of heater componentsis the same for both standard heaters and kit heaters, they are only covered in one place in this manual. See Chapter 22 formaintenance of heater components.

INTRODUCTION TO HOW TO USE TROUBLESHOOTING 0005 00

PURPOSE

The purpose of unit troubleshooting is to diagnose problems which are reported to unit maintenance. You should not beginunit troubleshooting until ALL operator troubleshooting procedures have been performed. You will perform four actions inunit troubleshooting:

(1) Before starting a troubleshooting task, verify that the reported problem is present.(2) After verifying the symptom, find the part that is causing problem.(3) Replace or adjust that part.(4) Check to make sure problem no longer exists, and that there are no other problems.

DEFINITIONS AND DESCRIPTIONS OF TROUBLESHOOTING PARTS

Troubleshooting tasks always have a beginning and an end. You will use task steps, test procedures, indexes, maintenancetasks, and other technical manuals to troubleshoot. Troubleshooting uses the following terms that are not used in other kindsof tasks:

1. FAULT: The part that is not operating correctly and is causing the problem.

2. SYMPTOM: The problem reported to unit maintenance.

3. STE/ICE: Diagnostic and test equipment used to troubleshoot at unit maintenance level. It isused to make measurements and find faulty parts in the carrier system.

4. VERIFY NO FAULTSFOUND:

After you have completed the corrective action, you must verify that no faults exist.If the fault condition still exists, then the fault is not fixed or there is another fault.If this happens, start at the beginning of the correct/appropriate troubleshootingprocedure until you find and correct all faults. Always operate the system and/orcarrier to make sure that you have corrected the reported problem. Iftroubleshooting does not identify a faulty part, the carrier is defective beyond thelevel of unit maintenance.
